Ferromagnetic (FM) microstructures in the FM metallic phase of La0.825Sr0.175MnO3 were examined by means of Lorentz transmission electron microscopy (Lorentz TEM) and small-angle electron diffraction (SAED). Microstructures of FM domains depend strongly on the crystal structures. The structural phase transition at 185 K accompanies with a drastic change of 180 degree FM domain structures from macroscopic wide domains to striped narrow domains. Lorentz TEM and SAED experiments revealed that a distribution of the magnetization in the striped FM domains is non-uniform and locally fluctuated.
